TO ALL WHOM IT MAY CONCERN:

I 'vBe it known that I, I. N. FORRESTER, of Bridgeport, Fairfield county, Connecticut, have invented a new and improved Rotary Swing; and I do hereby declare that the following is a full, clear, and exact description thereof, which will enable others skilled in the art to make and use the same, reference being had to the aecompanying drawings, forming part of this specifi-cation, in which- Figure 1 represents a. side elevation of my improved swing.

Figure 2 is an end elevation partly in section of the same.

Similar letters of reference indicate corresponding parts.

This invention relates to a new rotary swing, which is so arranged that the seats revolve both around a horizontal axle and around a vertical axle, whereby a very agreeable motion is obtained, and whereby the sense of giddiness generally created by the simple revolution around a horizontal axis is completely overcome or avoided. '.lhe invention consists in arranging one'or more frames, in each of which suitable seats are provided, each one around a horizontal axle, and in hanging the said axles upon uprights projecting from a revolving bed, andin mounting a gear-wheel or its equivalent upon each axle, 'said lgear-wheels meshing into the teeth of' a `gear-wheel -whieh is xed upon a. vertical post. When, now, the aforesaid bed is turned around the central vertical post, it will carry its appendages with it in its revolution, and the swings arethus also turned around the vertical axle, and at the same time also around their own horizontal axles, owing to the motion of the geen Wheels. i i

A represents a stationary bed, in the centre of which an upright post, B, is xed, carrying a bevelled-geai wheel,`a, upon or near its upper end. C isa bed, fitted loosely around the post B, and resting upon the bed A, as shown in iig. 2. D D are a series of uprights, strengthened by suitable braces projecting from and secured to the lplate C. In the uprights D- une bearings for two (more or les-s) horizontal axles b Zz, each of which has a gear-wheel, c, meshing into the pinion a, as shown. The inner bearings for these axles may, i'f desired, be in a block, d, which ts upon and turns on the upper end of the post B, as is clearly shown in iig. 2. E and E are the frames for the swings. The ,same are mounted upon the axles 1),'as shown, so as to revolve with the same. Seats F, of suitable construction, are suspended in any suitable manner from the frames E E. The' number of frames E E and of seats may be varied at pleasure, that of the former corresponding to the number of axles b.

It is evident that various devices for creating the combined horizontal and vertical revolving motion of a swing can bc substituted for that herein described; and I do not wish tocnne myself to the special mechanism described, but I do claim, and desire to secure by Letters Patent- 1. Rotating a swing -or swings at once around horizontal and vert-ical axles, substantially as herein shown and described.

2. The revolving platform C, arranged around the post B, and provided with uprights D D, in combination with the swing-frames E, und their axles b, all made as set forth.

The above specification of my invention signed b v me this 16th day of July, 1867.
